Background

The gear has a wide application range, and is an important part in various mechanical equipment, such as machine tools, airplanes, ships, watches, electric fans and the like used in daily life. There are various kinds of gears, including a spur gear, a helical gear, a spur bevel gear, a helical bevel gear, and a worm gear. Among them, the spur gears are more used and are simpler, also called as standard spur gears. The parameters relating to the formation of involute gear teeth, modulus, pressure angle, etc. will be described in the course of the description. The processing method of the spur gear is mainly described, and the processing method of the gear tooth form has two types. One is a forming method, that is, a method of cutting out tooth form by using a forming milling cutter completely conforming to the shape of the tooth socket of the gear to be cut, such as milling tooth; the other method is a generating method, which is a processing method for cutting out tooth shapes by utilizing the mutual meshing motion of a gear cutter and a driven gear.

Since gears are used in combination with gears to cause vibration and noise due to gear meshing noise caused by transmission errors, tooth hitting noise caused by backlash, and the like, it is necessary to have higher impact resistance than conventional applications.

In view of this, we propose an impact resistant gear.
